YELLOW OUT® is not an algaecide, herbicide or pesticide.  It does not contain quaternaries (foam), copper (stain), silver or poison.  No algaecide can match the safety of YELLOW OUT®.  YELLOW OUT® will not kill algae. However when YELLOW OUT® is used with EPA registered chlorine, cleanup is achieved quickly and economically.
What is a filter aid?
Answer: Filter aid is a generic term for a powdered product that, when poured into your skimmer, will coat the top of the sand in your filter, allowing the filter to catch those tiny bits of dead algae that are currently passing right through and causing the cloudiness. You can use diatomaceous earth, alum or whatever your local pool store recommends as a filter aid. Start with a small amount (about 1/2 cup) and then add only enough additional to raise your pump pressure about 1-2 pounds above the present reading on the gauge.

How long do I have to stay out of my pool after treating it with YELLOW OUT®?
Answer: YELLOW OUT® dissolves immediately, is neither an algaecide nor an herbicide and as such has no poisons in it. However, because of the concentration of EPA registered chlorine in your water after treatment, we recommend you stay out of your pool as long as you normally do after you shock or super-chlorinate your pool. How long you wait to swim after super-chlorination is a matter of
personal choice, but we recommend waiting at least 8 hours. After the EPA registered chlorine has dissolved completely, when the pool is clear and visibility is good, you may swim at your discretion.

If I have to treat my pool again within 7-10 days, do I need to add more YELLOW OUT®?
Answer: No, YELLOW OUT® usually stays in your water for 7-10 days after the original treatment unless it has rained or you have added additional water to the pool. So, if you need to retreat your pool within that time period, you need only raise your pH to 8.0 and shock the pool with 2 lbs. of EPA registered chlorine or 1 gallon of liquid chlorine (15%) per 10,000 gallons of water.
